I'm no millionaire, believe me, I'm an unemployed electrician!!! BUT, I was able to build a very nice Stage 2! Cost was about $20K plus the rest of the supporting parts so the car can handle the Stage 2: full billet rollerized trans, rear end, driveshaft, FAST XFI, Fuel Lines, Fuel Pump, CAS V2 front Mount, big injectors, frame bracing, etc, etc, etc. Point I'm trying to make is that there is a LOT more to it than just the motor. Once you get started on a Stage 2 build, you'l have a lot more to buy to back that motor up. Best idea for a primarily street car is get an off center block so everything pretty much bolts up like a stock block. You'll just have to make an oiling system for the block and weld a turbo drain back bung into the oil pan.
All said and done, it was the best $37K I have ever spent! That didnt even incude the cost of the car, brakes, suspension, interior, paint and body, etc. God I have to stop thinking about it otherwise I think I may cry!!!!!!
A nice thing about Stage cars over 109 cars is the value of your car is always going to be higher than the 109 cars.
